WesternPotash Corp. Reports a Composite Thickness of 24.4 Metres of PotashMineralization with a Grade of 18.2 Wt % K2O across Three PotashMembers from the Fourth Well at Milestone, Prepares for ExpandedDrilling and Seismic Program with Goal towards Resource Definition

Western Potash Corp. (the "Company") (TSX.V: WPX, FSE: AHE) is pleasedto announce that it has received the complete results from its firstphase drill program on the Milestone property in southern Saskatchewan.Gamma ray results have been reported in previous news releases for thefour wells drilled in the initial exploration phase and potash assayresults for the first well were reported in a June 15th, 2009 companyrelease. Highlighted in the fourth well is a 24.4 m compositeintersection of potash mineralization with a weighted average grade of18.2 wt % K2O across three potash members.

The 100% owned Milestone property, comprising 500 square kilometers, islocated 30 kilometers southeast of Regina, and southeast of Mosaic'sBelle Plaine Mine, one of the largest producing potash solution minesin the world. The potash mineralization encountered within the PatienceLake and Belle Plaine potash members in this drill program is similarin grade and thickness to those reported at the operating Belle Plainmine.

The Milestone-003 well is the fourth well drilled on the Milestoneproperty and is located approximately 12.5 km and 7.5 km to thesoutheast of the first and second well sites reported previously. Asummary of the results from this well are presented in Table 1.

Note: Total intervals noted in this release are composites. All drillintercepts noted in this release are considered the true thickness ofthe mineralization; as the salt beds are relatively flat-lying anddown-hole directional surveys indicate the hole was essentiallyvertical upon intersecting the salt and potash sequences. The corerecovered from this hole was logged, photographed, split, and sampledat the Company's secure core storage facility on the property. Allsamples were handled in accordance with the Company's Chain of Custodyprocedures. The half-split core samples from the wells were analyzed atthe Saskatchewan Research Council (SRC) Laboratory in Saskatoon. TheLaboratory has been certified by the Standards Council of Canada (SCC)to conform to the requirements of ISO/IEC 17025:2005 (CAN-P-4E).

The Company is very pleased with the potash grades intersected in thePatience Lake and Belle Plaine potash members reported for theMilestone-003 well, as these are considered particularly exceptional.In addition, these potash hosting members have very low carnallite andlow insoluble contents, which is also very encouraging as they arecritical factors for developing a solution mine. The grades reportedfrom the Esterhazy member are lower in comparison to grades reportedfrom the same member in previous wells. Also, the carnallite contentwithin the Esterhazy potash member is considered too high for effectiveeconomic extraction of potash in a solution recovery process.

The potash assays results from the Milestone-003 well support theCompany's decision to accelerate a resource definition program in thevicinity of this well as reported in the July 23, 2009 press release.

The Company is currently planning and permitting an additional 5 wellresource definition drill program to define the grade, thickness, andextent of this higher grade zone within the Patience Lake and BellePlaine members. A 2D seismic survey over this priority area has alreadycommenced. Furthermore, a 3D seismic survey will also be carried outfollowing the resource definition drill phase with the goal tofast-track and establish an NI43-101 compliant resource. The Company'sboard has approved an $8.5 million CAD budget for this program.

The Company is also pleased to report results from the second and thirdwells drilled on the property (Milestone-002, and Milestone-002Arespectively), a summary of which is presented in Table 2.Milestone-002 was drilled 5.25km to the south east of the first well,and encountered an anomaly not apparent in the 2D seismic data thatremoved most of the potash mineralization in the Patience Lake Member.This anomaly was likely due to local structure and water ingressresulting in localized dissolution.

The Milestone-002A well was directionally drilled from the same wellsite as Milestone-002, intersecting the potash beds 800m to the northof the vertical second well. The Company decided to drill thisdirectional hole to test the theory that the anomaly observed inMilestone-002 was a local anomaly. Geological observations, gamma raylogging and geochemical results have indeed confirmed this theory.

Results from the Milestone-001 and Milestone-002A wells demonstrateregional continuity of all three potash members between these wells.While these results show positive potash mineralization, the Company iscompelled to focus its initial resource definition in the vicinity ofthe Milestone-003 well, where higher potash grades and betterthicknesses within the Patience Lake and Belle Plaine members have beendemonstrated.
